Do these results sound reasonable? I mean is this consumption acceptable?

[lorebett]

Are the following benchmarks sound reasonable concerning power consumption?

This is for a DELL Latitude E5510:

In Idle state, I have measured
- 28.1 Watt in Ubuntu 11.04 and
- 15.0 Watt in Windows 7

Under Load, I get
- 50 Watt in Ubuntu 11.04 and
- 38 Watt in Windows 7

Measurement was done with a precise device when battery was fully loaded.

Please upgrade your kernel to 3.2.5 before complaining about battery life. If your battery life is still poor with 3.2.5+ then feel free to report it here.
